USB2ANY: Regarding the self-developed development board using DLPC3436+DLPA2000, I would like to use I2C communication to debug and switch images

Part Number: USB2ANY
Other Parts Discussed in Thread: DLPC3436

May I use this USB2ANY tool for reading and operation? Currently, I am using this reading software as DLP_Hardware_Diagnostic_Program_v1.1.Then connect our self-developed board, as shown in Figure 1 and 2.What is the reason why I cannot be recognized and read by software?How can I achieve the requirements of my title? I hope to receive your reply as soon as possible.

您好

It looks like the USB2ANY has no firmware on the controller. Sometimes USB2ANY DLL (shipped with DLP tool and other TI software) has trouble recognizing unprogrammed controllers. I recommend using the discrete firmware loader binary in the USB2ANY SDK to flash the firmware onto the unprogrammed controller, then try the DLP tool again.

DLP tool uses USB2ANY firmware version 2.8.2.0. SDK link for v2.8.2.0 below:

Hi Daniel,

Thank you for your reply.I have downloaded version 2.8.2 as you suggested.However, I am currently using a DLPC3436 display board, and I2C communication is normal. However, I still cannot write I2C properly in the SDK. I have confirmed that the pin positions are not connected incorrectly. Can you help me point out any other reasons.

Thank you.

Cindy

I want to send commands through I2C, but I keep receiving feedback that I only use I2C and there are no pin conflicts.Hope to receive a reply as soon as possible.

Thank you.

您好

USB2ANY connection in the user's guide for the DLP tool appears to require 3.3V and GND connection from USB2ANY. Do you have all four wires connected?

Since 3.3V is required, this implies the internal 3.3V supply and on-board I2C pullups are used. Try setting 3.3V supply on, and set "Enable pullups", and see if I2C responds.

Hi Daniel,

I have already made the necessary modifications and connected four wires, but still cannot perform I2C command operations. The error displayed in the following image is causing me great distress. May I ask what else could be the reason for this?SDK and DLP_Hardware_Diagnostic_Program_v1.1 ,the manuals for these two software only explain the operation, but there is no reason for the error.The picture you gave me is not displayed, it is damaged.

Thank you
